Build a bond wall
- Instruct students who are having difficulty to build a bond wall of 10 using one of each block from 1 to 10 and an additional 5 block.
- Cover this with a piece of paper.
- Students predict the answer to the subtraction spun, then lift the paper to find the related bond and confirm/correct their answer.
- Replace the piece of paper covering the blocks in preparation for their next turn.
Place part-part-whole diagrams next to students, for them to refer to, whilst completing the activity with blocks in a jumbled pile. These diagrams can be useful supports for students with memory or processing difficulties.
